PACKAGE-FORMING MACHIN.

Application led March 23, 1914.

T0 all fev/1.0m it may concern Be it known that we, PAUL H. GRIMM andFRANK L. Cooks, both citizens of the United States, residing,respectively, in Glen Cove, in the county of Nassau and State of NewYork, and borough of Brook lyn, county of Kings, city and State of NewYork, have invented certain new and useful Improvements inPackageForming Machines, of,V which the following is a specification.

This invention relates to package-forming machines and has for an objectto provide mechanism for incorporating in a container or package whenthe same is in process of manufacture, a sheet for adding to thesecurity afforded by the container. This is preferably a liningimpervious to moisture, and may bev of some suitably prepared paper,thus tending to preserve from deterioration the material which isafterward placed in the package.

The illustrated embodiment of the invention is in one aspect in thenature of an improvement on the Smyser machines an illustration of anexample of which is to be seen in U. S. Patent No. 505,857, issuedOctober 3, 1893.

Although the parts for feeding the additional or interlining sheets areadapted to be supplied to existing machines, and when present may beused or not as occasion may demand, and may be removed entirely from theparts making up the simpler mechanism.

without disassembling the latter, yet the new parts and the old form aunitary organization cooperative in effecting new results, and producinga new product in which the new elements enable the old elements toperform new functions, thepresence of the new elements enabling the oldelements to produce a new product.

In the drawings accompanying this specification a practicable embodimentof the invention is illustrated in -whicli,-

Figure l is a side elevation of a portion of a package forming machine,certain of the parts being broken away to illustrate the relation of theparts lying beyond; Fig. 2 is a plan view of a portion of the deviceillustrated in Fig. 1, andis taken on a plane at about the line 2-2 insuch figure. 'f

That portion of a package forming machine or packaging machine whichsupplies the paper wrappers to the folding or forming devices, isillustrated herein.

There is shown at A a stack of wrappers in position to be liftedandtransferred to the folding device. This stack is shown upon asuitable stack support or holder A which is advanced automatically insome suitable manner, in the present instance a screw A2 being providedfor this purpose; such feeding however being no part ofthe presentimprovement it is not described in detail;

The object of the mechanism illustrated is to feed forward at regularintervals sheets a from the stack A and to apply to or impose upon theuppermost sheet of the stack an interlining sheet 5. The sheet yb is fedforward. over the topmost sheet a of the stack into such a position thatthe lifting and forwarding device will engage both sheets simultaneously-and lift them and transfer them. In the Smyser machine above referredto the uppermost sheet of the stack is engaged by pasting mechanism, thepaste being utilized in the transferring, and after the sheet has beentransferred to the folding device such paste is Iutilized for thepurpose of'holding the wrapper in its folded position. In the presentmechanism the added sheet is placed in such a position relatively to theposition of the uppermost sheet in the stack and to the working point ofthe pasting and transferring mechanism,

that the im o'sed sheet shares the paste with the sheet of the stack.The two sheets are moved simultaneously and held together and are so fedor supplied\to the folding device.

There are shown four pastinga'nd transferring devices C whichare'caus'ed to revolve step by step in steps of90 degrees in ahorizontal plane, and are also caused to reciprocate vertically,-between the `steps taken, from the horizontal plane. Each of thesepasting devices is shown carried by an arm c, which arms are fast upon aplate c fast upon a vertical shaft C', which'shaft is mounted insuitable bearings in the framework of the machine, and is held in itsupward position by yielding means. Each of the plates C is provided uponits underside with paste receiving feet o2 for engaging the pastedsurface of paste disk c3, which `paste disk is caused to rotate and itssurface be thereby supplied with paste from a reservoir c4. The stackholder A is disposed at a position below one of the between steppositions of the plates C, and the paste disk c3 is disposed at anothersuch position, so that these two portions of the device are disposed atangles of approximately 90 degrees about the shaft C. 'In the mechanismillustrated the point of delivery of the sheets from the pasting andtransferring mechanism is the matrix H disposed substantiallydiametrically opposite the position of the stack holder A The liningpaper carried by the roll B is illustrated of less width than are thesheets a (see Fig. 2) and the lining paper is fed over the stack so thatits forward edge comes to rest prior to reaching the forward edge of theuppermost sheet upon the stack, so that there is exposed a' margine onthe upper surface of the uppermost sheet of the stack at three edges ofthe sheet 6. The pasting feet c2 are of such area that they engage thisexposed margin and the edge of the sheet 6 adjacent thereto (see dottedlines in Fig. 2). When such feet are covered with paste and aredepressed upon the superposed sheets a and 6, the paste which otherwisewould be applied to the surface of' sheet a is shared by it with thesheet 6, and upon the rising of the pasting device the two sheets areraised and transferred together.

Suitable mechanism is provided for unwinding and advancing the paperfrom the roll B. In the present instance the sheet or stock of paper ispushed forward by rotating the roll and by means of suitable rollerguides is again pushed forward over the stock and the sheet is theresevered from the stock. The roll is shown mounted upon aI 6* pivoted toone end. 6's of a bell crank, the y other end 6 of which is operated bymecha nism presently to be described.

A certain amount of adjustable overthrow is provided for the pawl 63. Itis shown longitudinallyumovable in the pitman 64 and 1s held in itsadjusted position by means of a .suitable set-screw 67. By this meansthe amount of movement imparted to the roll by uniform oscillations ofthe bell-crank 6'5 68 may be adjustably varied as desired. Anantifriction roll 68 is provided for holding the pawl 63 to its work.One great diiculty vexperienced in this class of mechanism is overcomingthe inertia of the roll of paper B, and guarding against the momentumwhich it acquires when advancing the stock of paper step by step.Considerable leverage is aiforded by the present mechanism, and thepaper is started forward and advanced without undue strain to the partsof the machine or to the paper itself, and the paper 1s accuratelymeasured, and positively stopped at the predetermined position.

The stock of paper from the roll B is led to idler rolls 69, and to apair of guiding and forwarding rolls 61 611 which, in the presentillustration are positively driven. In the present illustration thelower roll is made of smooth brass and the upper roll is made of smoothrubber. A support 612 is provided for the paper in case the amount fedfrom the roll is in excess of the demand of the rolls 610 611. A guide613 is provided in front of the rolls 61 611 for similar reasons. At thedischarge side of such rolls a funnel-shaped guide 614 is provided.Suitable shears are provided for severing the stock adjacent the stackA. Such shears in the present illustration comprise a fixed blade 615and a movable blade 616. A supporting plate 61T is provided at the stackside 0f the shears for supporting the rear edge of the sheet 6 afterthis has been severed from the stock. A coiled spring 618 is providedfor normally holding the shear blades open. Irregularities frequentlyoccur in the rolls of lining stock B, sometimes in the cores on whichthe rolls are wound, sometimes in the paper itself being thicker at oneside than atvthe other; to assure the accurate feed, one of the rolls 69in the drawings the upper of these rolls, is mounted in a shiftable box69, engaged by adjusting screws 6"1 691 whereby 'such irregularities orinequalities may be rectified by adjusting the position of such roll.

The main driving shaft of the machine is shown at D, and is driven by apulley d. This shaft is shown havingfixed upon it a worm d meshing witha worm-wheel d2 which is fast with a shaft d carrying a bevel gear d4meshing with a bevel gear als which is fast on the cam shaft df. Uponthe cam shaft d are mounted the driving cams of the machine. The camwheel Z7 is provided with a M for aeaeiving das .antifrictiou roller inthe end of a lever d, whach lever is connected by means of a linkd" withan arm c carried yby -a hub -c loose on the shaft C. The plate c isshown provided with four holes c1 for receiving a lug cnl on the underside of the arm c5 when the shaft l is in its elevated position. Thethrow of Ythe lever d is so adjusted and -the connections soproportioned that at each rotation of 'the `cam shaft the plates C arerotated through, an angle of 90 degrees. A cam wheel d10 is also mountedupon the cam shaft and is provided with a groove for receiving theantifriction roller -of a lever dn which is connected by means of a linkd with a head member d 'carried by the upper end of the shaft C. The camgroove and .associated parts are so proportioned and timed that afterthe plates C have been stepped around 90 vdegrees in a horizontal.plane, the plates will be forced downward, bringing the paste feet c' ofone pasting and transferring plate in engagement with the surface of thepaste disk c3, and bringing the paste 4feet -of the preceding `plate inengagement with the superposed sheets a b at the top of the stack. Thehead d is provided with an opening in eachcorner, which openingsregister with guide pins d suitably carried by the machine frame andprovided with conical ends for :the pur ose of justifying the positionof the plate c at, the beginning of its descent and for'guiding it in atrue line. The shear blade b1 is provided with an upstanding end b1located in the path of movement of shear actuating devices b carried bythe plate c" upon the descent of the shaft C.

There is shown mounted on the driving shaft D a worm `e meshing with aworm wheel e mounted upon a shaft c2, which shaft is shown provided witha bevel-gear e3 meshing with a bevel gear e'1 fixed upon a shaft e5,which shaft is the driving shaft for intermittently feeding the stockforward for supplying the interlining sheets b. The continuouslyrotating driver E for such portion of the mechanism is shown fast uponshaft e". This driver in connection with suitable engaging mechanism istimed for stepping the gear wheel e6 forward at suitable times to feedthe interlining sheets over the uppermost sheet of the/stack at suchtimes as the pasting andtransferring mechanism is out of the path ofmovement of the oncoming interlining sheet. This mechanism comprises auintermittent clutch. The gear wheel e is mounted free upon a iange e'(Fig. 7) which 'formsl a part of the bearing for the shaft cs and thedriver E. This flange is carried by a plate e8 securely fastened to theframework of themachine. The driver IE is of disk `formation cut awayand having la finger e9 for engaging, when dll @EGW fara@ the 10 @M- bylthe wheel ce. in the present illustration there are foar of these pinsvset at angles of 90 degrees one to the other about the axis one of thepins to ride up this inclined face f and on :to the 'fiat portion of thetrack, which will then bring the outer end of thc pin into gpsition tobe engaged by the finger e. The ger will then, move the wheel e forwarduntil .the pin which it is engaging runs oi the end o the track-and isreturned tov idle -position by means of lits spring.- This will thenrelease the wheel e? from the engagement of the actuator E and permitsuch actuator vto move forward idly. -Just prior -to the pin which is.in engagement with the finger running off the track, -the pin behind itruns up on the inclined surface and on to the level surface of the trackand is in position to engage the finger e9 upon its next rotation, thatis, the finger e9 is in engagement with a pin through 90 degrees of itsr0- tation and moves from engagement with a pin and idle during 270degrees of its rotation. One portion of the plate forming the actuator Econstitutes a cam e13 upon its edge. This portion of the plate isprovided with a raised rib e for clearing the pins el and their pockets.The serrated face of the cam e13 actuates the pawl b3 through the rollf5, bell crank b5 b and pitman b4.

A brake F -is provided for the roll B, or its carrier, and engages afriction face f fast with the shaft which carries the roll material.This brake is actuated by means of the camface e. The depressionsforming the serrations for actuating the pawl b3 are not sufficientlydeep to' permit the brakes to become active. The brake is carried by lastem f2 and is pressed toward its work by means of a coiled spring f3.It is raised by means of the lever 7'* which carries a roll f5 runningupon the cam facev els. The lever f is pivoted at f, and is connected tothe brake stem y"2 by means of a link f2". Adjusting means is providedfor the brake in the form of a nut ffl mounted upon the stem f.

It has been found, desirable to assist the forwardin rolls in advancingthe stock from whic the lining sheets b are severed. To this end theroll B is unwound or rather it is rotated in such a direction that thematerial unwinds from it to approximately meet the demand of theforwarding .rolls by the pawl and ratchet mechanism above described. Theforwarding rolls are supported in the present instance by means of abracket 621. secured to the main frame. The rolls are providedrespectively with intermeshingpinions 622 623. The rolls are rotected bymeans of housings 624 625; 624

1s shown secured directly to the bracket 6"1V and the housing 625 isshown secured to a plate 626 which is adjustably secured by means ofset-screws to the bracket. Setscrews 6" 62s are provided for engagingthe .plate 6L6 and the end of the housing 6"5 for forcing the rollstogether.

As stated above the roll 61 is provided on its outside with a rubberface and the roll 611 is provided with a brass face. In the presentgearing at each period of movement o f the sprocket wheel G theforwarding rolls will 'advance 5`l revolutions and accu- 'ratel}7measure the lining sheet 6. The rolls 610 611- are shown driven in 'thefollowing manner: One of the rolls, as for-instance the lower roll 611,has fast with it a sprocket wheel g (Fig. 6) over which runs a sprocketchain g1 running over the driving sprocket G, which sprocket has fastwith it a pinion g2 meshing'with an idler g3 (Fig. l) which meshes withthe spur gear e which 1s intermittently' driven by the continuouslyadvancing actuator E. g2 g3 are mounted on shafts g* g, 'and are eachprovided with a hub for the purpose of brake engagement. The brake g iswedge-shaped and provided with .a plunger g". The brake is held to itswork by means of a coiled spring g8. The plunger g7 is articulated tothe lever f* Ywhich actuates the brake F and is actuated concurrentlytherewith. A drag brake g9 is shown (Figs. 3 and 4) continuously inengagement with the hub associated with the sprocket wheel G. 'A handlever f7 (Fig. 6) is provided for raising the brakes when it is desiredto rapidly feed forward'the paperfrom the roll by hand in setting up themachine or when it is desired to remove one roll and replace it byanother. A catch f8 is lshown for engaging the hand lever and holdingthe brakes in their inoperative position.

Each of the pasting and transferring devices stops in turn over thematrix H, the matrix and associated parts here illustrated beingsubstantially those illustrated' in the Smyser patent above referred to.Upon the downward movement of the transferring devices the interposedsheets a 6 are placed upon thel upper surface of the matrix, 'whereuponthe stripper I descends and holds the sheet or sheets in position duringthe upward movement of the transferring device. The stripper isillustrated in dotted lines in Fig. 5. After the stripper and thetransferring 4device have been sufficiently advanced in their upwardmovement, the atrix H is advanced toward the formers The operation ofthe machine is substantially as follows z--The pasting and transferringdevices illustrated operate substantially in the manner set forth in theSmyser patent above referred to and their operation will not, in thispart of the description, be specifically'mentioned except in connectionwith the explanation of the associated parts, except to state that attime intervals thepastecovered feet c2 c`ome into position over; theystack A'and descend and rise and advance. At each descent thepaste-'covered feet will engage the uppermost sheet of the stack, applypaste thereto and utilize such paste in raising and forwarding theuppermost sheet of the stack. After a sheet a has been raised thepresent mechanism will supply beneath it one of'the extra lining sheetsas a 'rider f orthe uppermost sheet of the stack by forwarding thelining sheet to position. The mechanism for forwarding and severing therider or lining sheet is timed in such relation to the actuation of thepasting and forwarding mechanism that such rider sheet will be inposition for sharing with the uppermost sheet of the Stack theengagement of the lifting and forwarding mechanlsm. The shaft e5 for theactuator E of the sheet-supplying mechanism is shown driven by the sameshaft which drives the cam shaft d for controlling the horizontalstep-by-step movement of the pasting and transferring mechanism as wellas its vertical movement for engaging the sheet and lifting the same. Inthe position illustrated in Fig. l the paste-covered feet c2 are at theend of their upward stroke, having descended upon a sheet a at the topof the'stack, having Iimposed upon it a sheet 6, leaving a margin a1 forthe reception of the paste and Alifted the same. As is stated above, thefeet 02 are of sufficient area to apply paste to this exposed portiona1and to the adjacent edges of the imposed sheet 6. The next movement ofthe pasting and transferring mechanism is in a substantially horizontalplane, and during which movement the finger e9 of the actuator E istimed to come into engagement with the pin el which was advanced in itspath just prior to its disengagement from the pin with which it waspreviously in engagement. This engagement between the pin e1 and thefinger e9 causes the spur gear e to move forward 90 degrees, whichforward movement,

. upon its inauguration depresses the roll f and removes the brakes fromengagement with the hubs of the pinions g2 gaand from the friction faceof the holder for the roll of paper stock B. The forward movement maaar;

ofA the parts is then permitted.- Thedriver and reciprocates the-pawlb3, thereby advancing thelroll carrier step by step and causing-the'vmaterial to unwind therefrom and be fedforward to theforwardingrolls which then push the paper .Forward over. the stack A. After apredetermined amount of paper has been fedforward the cam e13 runs olfthe roller f5 whereupon the leverf, and the brakes respond to theirrespective springs and the actuating mechanismn and the paper-forwardingmechanism come to a standstill. The rollers b104 b positively positionand hold the sheet until itis severed. At the time the cam runs olitheroll f". the pin el", which liasbeen engaged by the iinger e9 forimparting the forwardmovement to the spurwheel e", runs off its track eand is drawn out of engagement with the finger by means of its spring.At about the time the forwarding rolls b1 b1? have been brought to resttheA pasting and transferring device is in position over the stack andlis then caused to descend. In its descent the shear-actuating foot b20-engages theend of the shear b and severs the sheet which has been placedin position at the top of the stack, and the continued descent ofthepasting device brings the feet c2 into engagement with thesuperposedsheets in the manner above described.- It isto be noted thatthe cam for effecting the unwinding of4 the paper from the roll B alsocontrols the brakes for the roll and for the forwardingy mechanism forthe material unwound.

It will be apparent that changes may be made in the mechanism within thescope of the claims without departing from the spirit of the invention.
